High Temperature Solenoid Valve for Steam Hot Water Thermal Oil Boiler Autoclave Chemical Reactor Suppliers Manufacturers

High Temperature Solenoid Valve

An automatic valve designed for controlling high-temperature fluids such as thermal oil and steam (medium temperature ≥ 300 ℃, up to 650 ℃), which achieves rapid on/off control of pipelines through electromagnetic force driven piston structure.

Core design features

High temperature resistance: The valve body is made of stainless steel/alloy material, suitable for medium environments of 300-650 ℃;

Zero leakage seal: metal hard seal or metal+fluoroplastic (PTFE) composite seal structure;

Anti burn coil: External heat dissipation module (air-cooled/high-temperature resistant material) ensures that the coil temperature is ≤ 85 ℃;

High pressure adaptability: piston pilot design, supporting pressure difference of 0.1-40MPa.
